Danfoss Nessie Water Motors

The Danfoss Nessie water motor program consists of the MAH, MVM and APM motors. MAH motors for high-speed applications are based on the axial piston principle. The MAH motor has a coated aluminimum housing with stainless internal parts.The MVM-motor is a new low-speed-hightorque water hydraulics motor designed according to the vane motor principle.

The MVM motor is hydraulically balanced to enable a high starting torque and smooth operation at even very low speed.

The SWPE is a high efficiency energy recovery unit for reverse osmosis filtration of seawater. Energy recovery is achieved by high-pressure brine from membranes being feed into the recovery device The unit consists of an APM motor and an APP pump, both connected to a double shafted electric motor.Energy recovery is obtained when high-pressure brine from the membranes is fed to the APM that converts the energy in the pressurised brine to mechanical energy to be re-used by the electric motor. As the APM has a fixed volumetric displacement, the recovery rate will be fixed.The SWPE are available in sizes from 4-30 m3/day with recovery rates between 20%-32%. Other sizes are available upon request.
